Yes... Couldn't resist because it is a huge step forward compared to my old amps! I'm happy
I guess it's time to make an enclosure...

An externally hosted image should be here but it was not working when we last tested it.

I was going to build the aleph 5 but i ditched it as i wanted more power and thought that i should just start investing in the aleph 2 instead. So how does it sound. ?
maybe i should start a aleph 5 Humm heh. now you got me thinking.
i think ill just finnish the aleph 2's first then go from there.

Jason,
Sound is much better then my old amps (Thel) The highs are bright, clear but not sharp, bass is twice as deep as with my old amps. It does not sound flat either, actually i'm really happy with this amp.
Since I have no experience with electronics, I consider it a great project. It worked right away. I'm planning to replace the 392 ohm restistor for a pot with a serie resistor to get rid of the dc-offset of a 180mV. The other channel has 30 mV offset.

Lowering the offset
Hello Jan,
The offset would be minimized if you would use
matched input IRF 9610 transistors.
The matching is very easy, and it can be done in a few minutes.
You can use attached circuit diagram for the matching mosfet
devices.
The 30 mV is ok, but with the good matched transistors, the
offset can be still lower.
The 180 mV is also not that too high like it's sound, but for the
DIY Aleph standard I guess that the most of the people would
try to lower this value also.
Best regards,
Kristijan Kljucaric
